Network, Wireless

Here is how to set up a wireless network. This example will demonstrate how to use WPA2-PSK method.

wpa supplicant

This example shows a non-broadcasted network, and use of WPA2 with a preshared key. network section:

network={
bssid='gatewaymacaddress'
ssid="'networkidname'"
scan_ssid=1
psk="networkpassword"
priority=9
proto=RSN
key_mgmt=WPA_PSK
group=CCMP
pairwise=CCMP
}

RSN signifies WPA2. key_mgmt, group, and pairwise are also common values to use WPA2. Giving the ssid allows the network to be found when it is hidden from scans.

Once the network is set up, bssid can inserted later, it can be found by

% ifconfig | grep bssid

rc.conf

hostname="mycpomputerhostname"
wlans_networkcarddriver0="wlan0"
default_router="ipaddress"   # example 192.168.1.254

Set the default network connection, to prevent it from guessing which network to use. Add mode, ssid, and bssid in the ifconfig line. The values typically match what's in wpa_supplicant.conf.

ifconfig_wlan0="mode 11g ssid networkidname bssid macaddressofnetwork WPA DHCP"

bssid or mode can be found by typing, optionally using grep

% ifconfig | grep mode

final steps

% service netif restart
% wpa_supplicant -i wlan0
